2019 INFINITI QX30 fuel cap

Malfunction Indicator light
(MIL) (yellow)
When the ignition switch is turned to the ON
position, the yellow Malfunction Indicator
light illuminates. This means that the system
is operational.
If the yellow engine malfunction indicator
light lights up while the engine is running,
there may be a fault, for example:
•In the engine management
•In the fuel injection system
•In the exhaust system
•In the ignition system (for vehicles with
gasoline engines)
•In the fuel system (including a loose or
missing fuel filler cap).
•In other monitored items, for example the
automatic transmission.
The emission limit values may be exceeded
and the engine may be running in emergency
mode.
CAUTION
Continued vehicle operation without having
the engine control system checked and re-
paired as necessary could lead to poor drive-
ability, reduced fuel economy and possible
damage to the engine control system.
Incorrect setting of the engine control system
may lead to non-compliance of local and na-
tional emission laws and regulations.
Have the vehicle checked as soon as possible.
It is recommended you visit an INFINITI re-
tailer for this service.
Distance warning light
(if equipped)
This light illuminates if the distance to the
vehicle in front is too small for the speed
selected.
If a warning tone also sounds, you are ap-
proaching a vehicle or stationary obstacle in
your line of travel at too high a speed. For
additional information see " Forward emer-
gency braking (FEB) system (if equipped)".
Electric parking brake
warning light
The red indicator illuminates when the elec-
tric parking brake is engaged.
If the red indicator light for the electric park-
ing brake flashes or is lit and/or the yellow
warning light for the electric parking brake is
lit, observe the additional messages dis-
played in the vehicle information display.
For further parking brake operation informa-
tion see "Parking brake".
Seat belt (driver and front
passenger) warning light
The seat belt warning light reminds you to
fasten your seat belts. The light illuminates if
the engine is started, all doors are closed and
the driver’s and/or front passenger’s seat
belt is unfastened. It will remain illuminated
until the driver and/or front passenger fas-
tens their seat belt. A chime will sound once
the vehicle is in motion, see "Seat belt re-
minder chime" later in this section. See "Seat
belts" for precautions on seat belt usage.
The seat belt warning light may also illumi-
nate if there are objects on the front passen-
ger seat. Remove the objects and stow them
in a safe place.

WARNING
•Gasoline is extremely flammable and
highly explosive under certain condi-
tions. You could be burned or seriously
injured if it is misused or mishandled.
Always stop the engine and do not
smoke or allow open flames or sparks
near the vehicle when refueling.
•Do not attempt to top off the fuel tank
after the fuel pump nozzle shuts off au-
tomatically. Continued refueling may
cause fuel overflow, resulting in fuel
spray and possibly a fire.
•Use only an original equipment type
fuel-filler cap as a replacement. It has a
built-in safety valve needed for proper
operation of the fuel system and emis-
sion control system. An incorrect cap
can result in a serious malfunction and
possible injury.

3-16Pre-driving checks and adjustments

•Keep your engine tuned up.
•Follow the recommended scheduled
maintenance.
•Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
•Keep all the wheels in correct alignment.
Improper alignment increases tire wear
and lowers fuel economy.
•Use the recommended viscosity engine oil.
For additional information, see "Recom-
mended fluids/lubricants and capacities"
WARNING
•Do not drive beyond the performance
capability of the tires, even with 4WD
engaged. Accelerating quickly, sharp
steering maneuvers or sudden braking
may cause loss of control.
•Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial), and tread pattern on all four
wheels.
•This vehicle is not designed for off-road
(rough road) use. Do not drive on sandy
or muddy roads that tires may get stuck
in.
•For 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to any
drive or reverse position with the engine
running. Doing so may result in drive-
train damage or unexpected vehicle
movement which could result in serious
vehicle damage or personal injury.
•Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) or
similar equipment even if the other two
wheels are raised off the ground. Make
sure that you inform the test facility
personnel that your vehicle is equipped
with 4WD before it is placed on a dyna-
mometer. Using the wrong test equip-
ment may result in drivetrain damage or
unexpected vehicle movement which
could result in serious vehicle damage or
personal injury.
•When a wheel is off the ground due to an
uneven surface, do not spin the wheel
excessively.

5-86Starting and driving

When performing any inspection or mainte-
nance work on your vehicle, always take care
to prevent serious accidental injury to your-
self or damage to the vehicle. The following
are general precautions which should be
closely observed.
WARNING
•Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from mov-
ing. Press the P (Park) button.
•Be sure the ignition switch is in the OFF
position when performing any parts re-
placement or repairs.
•Do not work under the hood while the
engine is hot. Always turn off the engine
and wait until it cools down.
•If you must work with the engine run-
ning, keep your hands, clothing, hair and
tools away from moving fans, belts and
any other moving parts.
•It is advisable to secure or remove any
loose clothing and any jewelry, such as
rings, watches, etc. before working on
your vehicle.
•If you must run the engine in an enclosed
space such as a garage, be sure there is
proper ventilation for exhaust gases to
escape.
•Never get under the vehicle while it is
supported by a jack.
•Keep smoking materials, flame and
sparks away from fuel and the battery.
•Never connect or disconnect either the
battery or any transistorized compo-
nent connector while the ignition switch
is in the ON position.
•On gasoline engine models with the
Multiport Fuel Injection system, the fuel
filter and fuel lines should be serviced by
an INFINITI retailer or qualified work-
shop because the fuel lines are under
high pressure even when the engine is
turned off.
•Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition switch is in the OFF position
and the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
•Always wear eye protection whenever
you work on your vehicle.
•Never leave the engine or the transmis-
sion related component harness connec-
tor disconnected while the ignition
switch is in the ON position.
•Avoid direct contact with used engine oil
and coolant. Improperly disposed engine
oil, engine coolant, and/or other vehicle
fluids can hurt the environment. Always
conform to local regulations for disposal
of vehicle fluids.
This “ 8. Do-it-yourself” section provides in-
structions regarding only those items which
are relatively easy for an owner to perform.
You should be aware that incomplete or im-
proper servicing may result in operating diffi-
culties or excessive emissions, and could af-
fect your warranty coverage.If in doubt
about any servicing, it is recommended you
have it done by an INFINITI retailer.
MAINTENANCE PRECAUTIONS
8-2Do-it-yourself

air conditioner after use is normal. If you
should notice any leaks or if gasoline fumes
are evident, check for the cause and have it
corrected immediately.
Radiator and hoses:
Check the front of the radiator and clean off
any dirt, insects, leaves, etc., that may have
accumulated. Make sure the hoses have no

rosive substances such as those used on icy
roads or to control dust. It is very important to
remove these substances, otherwise rust will
form on the floor pan, frame, fuel lines and
around the exhaust system. At the end of
winter, the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information, see
"Cleaning exterior".
